How to Clear Graph Data?

Two weeks ago I created a quick little bash script to monitor the free disk space on the Nagios server it self.
During its short development time I changed the
plugin output spec a lot.
Long story short I deleted one of the output values that I didn't need anyway and now the graph in XI have stopped working.
So my simple question is, how do I clear the graph data?
Long story:
The % value used to be the 3rd value, so when I deleted the 2nd value the % value was moved to be the 2nd value and thereby making this graph show a very high % number.
After the removal of the 2nd value, the graph simple stopped getting new data.

The performance data for graphs are stored in .rrd and .xml files on the system. If you delete those files, they will get re-created and display the current data after about 20 minutes.
Those files are stored in the following folder under the name of the host check.
Code: Select all
/usr/local/nagios/share/perfdata/<hostname>

That did the trick, thanks!
And wow that folder had a lot of crap. I mean information on all test/old hosts I had created and deleted.
Anyway, this can be closed if you want.

FYI the Performance Data Tool I created has a delete function that can find old files so you can delete them:

Upload it into Nagios XI via Admin > System Extensions > Manage Components.
Access it via the Tools menu.

Is it alright if we close this thread and mark the issue as resolved?
